Signing a Message to Verify Address Ownership in KomodoOcean

To prove ownership of an address without exposing your private keys, you can sign a message with your private key. By sending the signature, message and public address to be confirmed, someone else can verify the message and confirm you own the address.


If needed, import your private key via the debug window - 


Go to the Console tab, and enter the command 

importprivkey <your private key>


Then wait for the rescan to complete



Now you can sign a message with the imported address


Signing a message with your address


Open KomodoOcean, and select Sign message... under the File menu




  • Select or paste one of your wallet addresses in to the top text box (if you are confirming an address which is not in your Komodo Ocean wallet, you will need to import it into your wallet.dat in Agama native mode first)
  • Enter a message. This can be anything you'd like, but you'll need to send it to the person asking to verify your address.
  • Click the Sign message button to generate the signature.




If the address entered is not in your wallet.dat, you will get see the error message in the image below:




To prove ownership of the address, send the following to whoever is requesting confirmation:

  • Public address
  • Message
  • Signature


WARNING: Anyone you send the above information will be able to pretend they own the address by sending the information to someone else. Though they will not have access to funds in the address, it is still recommended to not reuse addresses.



Verifying the Message and Address 


After receiving an address, message and signature from someone, you can verify it through the "Verify message" tab under the File menu.
